There is something psychologically different about holding a stone in the palm of your hand compared with looking at an image of one on a screen. The stone has weight. Its temperature changes against the skin. Its surface may be rough in one place and unexpectedly smooth in another. A dried leaf offers its own sensory information: fragile edges, visible veins, shifting colors, perhaps the faint sound of its surface when touched. A piece of bark, a seedpod, sand, soil, a feather found responsibly, or a fallen branch can draw attention toward qualities that are immediate, physical, and difficult to rush past. When natural materials enter creative work, art-making can become not only an act of expression but also an experience of noticing.

This quality has particular relevance in art therapy. Psychological distress often pulls attention away from immediate experience. Anxiety can project the mind into imagined futures, while rumination repeatedly returns it to unresolved thoughts, mistakes, losses, or questions. Trauma-related distress can involve feeling overwhelmed by memories or reactions that make the past seem psychologically present. Grounding practices are commonly used to help people orient attention toward what is happening here and now, often through sensory information such as sight, sound, touch, smell, and awareness of the body. The U.S. Department of Veterans Affairs, for example, describes grounding as focusing on present sensations and the external environment when distress becomes overwhelming.

Natural materials fit naturally into this process because they provide rich sensory information without requiring sophisticated artistic skill. A client can trace the ridges of a stone, arrange leaves according to shape rather than trying to draw realistically, press bark into clay, create patterns with seeds, or simply spend several minutes examining the colors in a fallen leaf. These actions do not automatically regulate the nervous system, nor should contact with nature be presented as a substitute for appropriate psychological treatment. Yet research on nature exposure has repeatedly suggested associations with improved mood, attention, stress-related outcomes, and mental health, while an emerging body of art-therapy literature is beginning to explore what happens when creative expression and engagement with nature are intentionally combined (Bettmann et al., 2024; Gulbe et al., 2025; Jimenez et al., 2021).

The value of nature-based art therapy, then, is not simply that leaves and stones are attractive materials. It lies in the way natural objects can invite slowness, sensory attention, metaphor, imperfection, curiosity, and relationship with something beyond the self. A stone can become an anchor for attention. A broken branch can become a metaphor for injury without requiring the client to explain their own story immediately. A collection of leaves in different stages of change can open conversation about transition. Texture can bring someone back from abstract thought into direct physical experience. In skilled therapeutic work, nature is not merely decoration around the psychological process. It can become part of the process itself.

What Do We Mean by “Grounding”?

The word grounding is used in several different ways, which can create confusion. In psychological practice, grounding generally refers to methods that help a person reconnect with present experience when thoughts, emotions, memories, or physiological reactions feel overwhelming. This may involve noticing what can be seen in the room, identifying sounds, feeling the contact of the feet against the floor, describing the texture of an object, slowing the breath, or orienting to where and when one is. The National Center for PTSD includes present-focused sensory attention among grounding approaches used when people are distressed by trauma reminders.

This is different from claims that direct electrical contact between the human body and the earth produces particular medical effects. Although the same word is sometimes used for both ideas, nature-based art therapy does not need those claims in order to make psychological sense. When a therapist gives a client a smooth stone and asks them to notice its temperature, weight, edges, and texture, the useful mechanism is readily understandable: attention is being redirected toward immediate sensory information.

Imagine a client who arrives for a session after an exhausting week. She is sitting in the room, but mentally she is replaying a difficult conversation from the previous night while simultaneously worrying about what might happen tomorrow. If the therapist immediately asks for a detailed analysis of the conflict, the client may become even more cognitively activated. Instead, the therapist might offer a small collection of stones and invite her to choose one without needing to explain why. She turns several over in her hands, eventually selecting a heavy, flat stone. The therapist asks what she notices physically. “It is colder than I expected,” she says. Then she notices its weight, an indentation on one side, and a pale line crossing its surface.

Nothing dramatic has happened, and that is precisely the point. For perhaps thirty seconds, her attention is no longer entirely occupied by yesterday and tomorrow. She is noticing something that exists now.

Grounding does not require the difficult emotion to disappear. The conversation may still need to happen. The client may still feel anxious. The stone has not solved the problem. It has simply helped create enough psychological space for the person to encounter the problem while remaining more connected with the present.

Why Nature Can Capture Attention Differently

Environmental psychologists have studied the restorative potential of natural settings for decades. One influential framework is Attention Restoration Theory, associated particularly with Rachel and Stephen Kaplan. The theory proposes that directed attention, the effortful form of concentration used when we must deliberately stay focused despite distractions, can become fatigued. Natural environments may support restoration partly because they engage attention in a gentler, less effortful manner, a quality often described as “soft fascination” (Kaplan, 1995).

Berman, Jonides, and Kaplan (2008) provided experimental support for aspects of this idea. In their studies, participants who interacted with natural environments, including through a nature walk, showed improvements on measures related to directed attention compared with those exposed to urban environments. Their work should not be interpreted as showing that every walk through a park will automatically improve psychological functioning, but it contributes to a larger literature suggesting that natural environments can influence attention differently from highly demanding built environments.

This distinction becomes useful in an art therapy setting. A therapist could place twenty manufactured art objects on a table and ask a client to select one, but natural materials often invite another type of examination because they contain irregularity. Two leaves from the same tree are not identical. A stone does not have a perfectly manufactured surface. Bark contains cracks, shifting patterns, damaged areas, and unexpected forms. The eye can move across these details without necessarily needing to accomplish anything.

For a person whose attention is dominated by demands, deadlines, screens, notifications, or repetitive internal thinking, spending several minutes closely observing a natural object can function as a small interruption. The purpose is not to romanticize nature as inherently peaceful. Forests can feel threatening, insects may evoke fear, flowers can trigger grief, and particular landscapes can carry painful memories. Yet when a natural material feels safe and interesting to a particular person, it can provide a rich attentional object that asks for observation rather than immediate problem-solving.

This transition from solving to noticing is central to many grounding-oriented creative practices.

Nature, Rumination, and the Mental Loop

Rumination is different from productive reflection. Reflection can help someone understand an experience and decide what to do next; rumination tends to circle repeatedly around distress without producing meaningful resolution. A person may replay what they said, imagine what they should have done differently, repeatedly ask why something happened, or remain caught in self-focused thought long after the thinking has ceased to be useful.

Research has explored whether contact with nature may influence this process. In a frequently cited experiment, Bratman and colleagues (2015) found that participants who completed a 90-minute walk in a natural setting reported lower rumination than those who walked through a high-traffic urban setting. The nature-walk group also showed changes in activity in a brain region associated with self-referential processing. The study was relatively small and should not be treated as evidence that nature is a treatment for persistent rumination, but it provides an interesting indication that environment can interact with patterns of repetitive thought.

Creative engagement may deepen this interruption because the person is not merely present in nature but actively responding to it. Consider a client who has spent several days repeatedly thinking about whether she made the wrong decision by leaving a job. During an outdoor art therapy session, she is invited to collect, without damaging living plants, five naturally fallen objects that catch her attention. She begins scanning the ground. A curled leaf attracts her because one side is dark and the other almost golden. She finds a twig shaped like a letter, a small stone with a red patch, and two seedpods that make a faint sound when shaken.

For several minutes, her mind has a concrete task that is curious rather than evaluative. Later, if she wishes, the objects may become part of an artwork exploring the transition. Perhaps they will have symbolic meaning and perhaps they will not. Their first function was simpler: they changed where attention was directed.

The therapeutic usefulness lies partly in recognizing that a client cannot always think their way out of overthinking. Sometimes the route back into psychological flexibility begins through the hands, eyes, ears, and body.

Leaves: Working With Change Without Explaining It

Leaves are among the simplest natural materials to introduce into art therapy, yet their visual and symbolic possibilities are remarkably broad. They vary in shape, transparency, texture, fragility, color, age, and condition. They can be traced, printed, rubbed with graphite, incorporated into collage, arranged temporarily, photographed, pressed into clay, or simply examined.

Because leaves visibly change across their life cycle, they can naturally evoke themes of transition, aging, release, renewal, impermanence, or seasonal change. The therapist, however, should resist deciding that a leaf means any of these things before the client does. Nature-based metaphors are useful precisely because their meanings are open.

Imagine a client recovering from the end of a long relationship. During a walk, she chooses several fallen leaves, including one that is partly green and partly brown. The therapist might be tempted to say that the leaf symbolizes being “between the old and the new.” Instead, the therapist can ask what attracted her to it. She responds, “It looks like it can't decide what it is.”

Now the metaphor belongs to the client.

She may arrange the leaves in a circle, place the half-green leaf away from the others, or tear it in two. Each choice offers possibilities for exploration, but none needs to be decoded by the therapist. The value lies in allowing an external object to carry a question that may be emotionally difficult to approach directly.

Leaf rubbing offers another, quieter application. The client places a leaf under paper and slowly moves a crayon or graphite stick over the surface until the veins emerge. The image was always structurally present, but it becomes visible gradually through sustained contact. For some clients, the repetitive movement itself may feel settling. For others, the unfolding pattern may prompt reflections about things becoming visible over time.

Again, the activity does not need profound symbolism to be worthwhile. Sometimes noticing the veins of a leaf for five minutes is enough.

Stones: Weight, Boundaries, Stability, and Personal Meaning

Stones have qualities that make them particularly useful for tactile grounding. They are usually durable, relatively stable, and easy to hold. Their weight provides clear proprioceptive information, while their surface can range from smooth to sharply textured. A client experiencing high emotional activation may find it easier to describe a stone's temperature and weight than to describe an internal state immediately.

A simple exercise can begin by offering several stones and asking the client to choose one according to touch rather than appearance. The person might close their eyes if this feels safe and explore the stones one at a time. Which is heaviest? Which fits most comfortably in the hand? Which texture feels pleasant, irritating, interesting, or neutral? After selecting one, the client might draw its contours, paint on its surface, wrap it in thread, build a clay form around it, or leave it exactly as it is.

The stone can also become part of symbolic work. A client overwhelmed by responsibilities might choose several stones to represent the burdens they feel they are carrying. Instead of creating a written list, they physically place each stone into a bowl or bag. The weight becomes perceptible. The therapist might then ask whether every stone belongs to the client, whether some can be placed elsewhere, or whether one responsibility feels heavier than all the others combined.

A different client might reject the metaphor entirely and say, “I don't want these to represent burdens. Stones remind me of the beach where I used to go with my grandmother.” That response is equally valuable. Natural materials do not come into therapy as psychologically neutral objects. They carry personal, cultural, geographical, and relational meanings.

The therapist's task is therefore not to announce that stones mean strength or stability. It is to ask what this stone means to this person, at this moment.

Texture as a Doorway Back Into the Present

Sight dominates many modern activities. We look at phones, laptops, televisions, road signs, documents, photographs, and interfaces throughout the day. Art therapy already broadens experience by inviting the hands into expression, but natural materials can intensify this tactile dimension because their surfaces are rarely uniform.

A texture-focused exercise might include bark, smooth stones, dried leaves, seedpods, sand, untreated wood, shells collected legally and ethically, clay, or plant fibers. The client is invited to explore each material slowly and describe sensory qualities without needing to evaluate them as pleasant or unpleasant. A surface can be rough, cool, flexible, brittle, ridged, soft, heavy, or uneven. The person may notice that certain textures evoke immediate emotional reactions.

This type of sensory orientation aligns with psychological grounding approaches that redirect attention toward present sights, sounds, smells, and tactile sensations. The exercise should nevertheless be adapted carefully for clients with trauma histories, sensory sensitivities, neurodivergence, chronic pain, contamination fears, or other experiences that may make particular textures uncomfortable. Grounding is not grounding if the material itself makes someone feel less safe.

For a client who does enjoy tactile exploration, texture can become an alternative to emotional vocabulary. Someone who cannot answer “How does your anxiety feel?” may immediately choose a thorny seedpod and say, “Like this. I can't hold it without constantly adjusting my hand.” Another client may press their fingers into clay and describe their exhaustion as “heavy and sticky.” The metaphor originates in sensation rather than abstract analysis.

This can make an internal experience feel more tangible and therefore sometimes easier to approach.

Making a Nature Mandala Without Chasing Perfection

Arranging natural objects into a circular or repeating pattern is a familiar creative practice, and in therapy it can support sustained attention, choice, sequencing, and observation. Leaves, stones, petals already fallen from plants, twigs, seedpods, and other responsibly gathered materials can be arranged temporarily on the ground or on a tabletop.

The most useful therapeutic framing is usually process-oriented. The client does not need to produce a beautiful photograph for social media or create perfect symmetry. They might begin with one stone and simply respond to what comes next. Perhaps the arrangement becomes balanced; perhaps it remains irregular.

For someone struggling with perfectionism, this temporary form can be particularly interesting because it cannot necessarily be preserved. Wind may shift a leaf. The materials may later be returned to where they were found. The client can practice investing attention and care in something without requiring permanent ownership of the result.

A perfectionistic client may initially spend most of the session searching for identical leaves. Rather than instructing them to stop, the therapist could become curious about what would happen if two visibly different leaves were placed next to each other. The client's discomfort may become more psychologically relevant than the mandala itself.

For another client, order may genuinely be soothing rather than rigid. Creating a repeating pattern may help organize attention during a chaotic period. The same activity can therefore serve very different therapeutic functions, depending on the person.

Bark, Clay, and the Art of Impressions

One especially rich way to combine conventional art materials with nature is through impressions. Bark, stones, leaves, shells, seedpods, and other textured objects can be pressed gently into clay to create patterns. The natural material can then be removed, leaving its trace behind.

This simple process can open a conversation about presence and absence, influence, memory, and what remains after contact. It may be particularly resonant in grief work, although it should never be introduced with a predetermined interpretation. A grieving client might notice that the leaf is gone but its structure remains in the clay and connect this spontaneously to the person they lost. Another client may simply enjoy experimenting with the patterns and experience no symbolic meaning at all.

Both responses are legitimate.

The exercise also offers a tactile sequence: press, feel resistance, remove, observe. It asks the person to pay attention to pressure. Too little and the impression barely appears; too much and the clay may distort. For someone who tends to rush, the activity can encourage adjustment through direct sensory feedback rather than criticism.

The material teaches something through interaction. The client learns not because the therapist explains the “correct” amount of pressure but because the clay responds.

A Five-Senses Nature Page

A practical grounding-oriented art exercise can begin outdoors, beside an open window, in a garden, or indoors with responsibly collected natural materials. The client divides a sheet of paper informally into areas representing what they can see, hear, touch, smell, and, where appropriate and safe, taste. Rather than writing lists, they respond visually. A bird sound might become a series of repeating marks. The roughness of bark might be represented through charcoal. The smell of damp soil might suggest a color. The movement of grass in the wind might become a set of flowing lines.

The exercise places attention at the meeting point between external sensation and internal response. It is not about creating an accurate record of the environment. It asks, What happens inside me when I pay attention to what is around me?

This distinction can be useful for someone who experiences anxiety. The client may discover that they were so focused on an upcoming conversation that they had not heard birds outside the window, noticed the air temperature, or felt the chair supporting their body. After the activity, the concern has not vanished, but the client's experience is no longer composed entirely of the concern.

Present-moment orientation is valuable precisely because distress and safety can sometimes coexist. A person can be worried and still feel the smooth surface of a stone. They can be grieving and still notice sunlight on a leaf. They can remember something painful while also recognizing that they are currently in a therapy room, sitting in a chair, breathing, and looking at a tree outside the window.

The purpose of grounding is not denial. It is orientation.

Natural Materials as Metaphors for Resilience

Nature offers powerful metaphors, but therapeutic work becomes problematic when those metaphors are forced. A therapist may look at a damaged tree and see resilience; a client may see danger. Someone may experience falling leaves as peaceful, while another associates autumn with the anniversary of a death. A flower opening might represent hope to one person and painful fertility struggles to another.

This is why nature-based art therapy works best when metaphor is discovered rather than prescribed.

A therapist might bring several natural objects into a session and ask, “Does anything here resemble something about your experience?” A client chooses a branch that has broken and healed around the damaged area. They say, “It didn't go back to how it was. It grew differently.” This becomes a powerful reflection because the client found it themselves.

The therapist can then ask what “growing differently” means in relation to their own life. Perhaps the client is recovering from illness and is tired of people promising that they will soon “get back to normal.” The branch offers another possibility: recovery does not always mean returning to a previous form. Sometimes adaptation changes the shape of life.

Another client may choose a stone precisely because it appears unchanged. “I feel like everyone expects me to transform,” they say. “I just want to be allowed to exist for a while.”

Nature is spacious enough to hold both metaphors.

Nature-Based Art Therapy Is More Than Taking Therapy Outdoors

Eco-art therapy and nature-based art therapy extend beyond simply relocating an ordinary art session to a park. The American Art Therapy Association has described eco-art approaches as intentionally integrating natural environments, natural materials, ecological awareness, sensory experience, and creative expression. A recent scoping review by Gulbe and colleagues (2025) similarly identified nature-based art therapy as an emerging approach in which nature may enter through the therapeutic setting, materials, artistic process, and the client's relationship with the environment. The review found themes including emotion regulation, stress management, self-discovery, social connection, trauma and grief work, creativity, and environmental sustainability, while also emphasizing that the research base remains small and further evidence is needed.

This distinction protects against overstating what is known. The broader literature on contact with nature is much larger than the specific research on nature-based art therapy. Reviews have linked nature exposure with a range of health and psychological outcomes, including mental health, cognitive functioning, and stress-related measures, but researchers also note substantial variation in how nature exposure is defined and studied (Jimenez et al., 2021). More recent meta-analytic work examining adults with mental-health symptoms has likewise reported beneficial effects while highlighting differences among settings, activities, study designs, and populations (Bettmann et al., 2024).

It is therefore more accurate to say that nature-based art therapy brings together two psychologically meaningful domains, creative expression and nature engagement, rather than claiming that combining them automatically produces a specific therapeutic outcome.

Nature Connectedness and the Experience of Belonging

Grounding is often described in very immediate terms: notice five things you can see, feel your feet, name the sounds around you. Nature-based work can include this present-focused function while also opening a broader psychological question: What do I belong to?

Research on nature connectedness examines the extent to which people experience a subjective relationship with the natural world. A meta-analysis by Capaldi, Dopko, and Zelenski (2014), drawing on 30 samples, found a small but significant association between nature connectedness and indicators of subjective well-being, including positive affect, vitality, and life satisfaction. As with all correlational findings, this does not demonstrate that simply increasing nature connectedness will automatically produce happiness, but it supports the idea that people's psychological relationship with nature may be relevant to well-being.

Art can make that relationship more personal. A client might create a map of places in nature that have mattered across their life: a grandmother's garden, a tree outside a childhood window, the sea visited during holidays, a city park discovered during a lonely year, or even a houseplant cared for during illness. What begins as a nature-themed artwork becomes an autobiographical map of safety, identity, memory, attachment, and place.

For people experiencing isolation, this may expand the idea of connection without suggesting that nature can replace human relationships. A person may still need friendship, community, family, or therapeutic support. Yet they may also recognize that belonging has environmental dimensions: particular landscapes and living systems can become part of how people understand home.

Bringing Nature Inside When Outdoor Access Is Limited

Nature-based art therapy should never assume that everyone can hike through a forest, sit on the ground, tolerate weather changes, or access green space. Disability, chronic illness, allergies, mobility limitations, institutional settings, unsafe neighborhoods, climate, sensory sensitivities, and financial circumstances can all affect access.

Fortunately, engaging nature in art therapy does not require wilderness. The American Art Therapy Association has described bringing natural materials such as leaves, branches, shells, seedpods, and stones into indoor studio environments as one way of incorporating ecological art therapy when outdoor work is impractical.

A windowsill plant can become an observation subject across multiple sessions. A bowl of stones can provide tactile materials. Fallen leaves can be collected near a building entrance. Photographs of personally meaningful natural locations may be incorporated when direct access is impossible, although physical and photographed nature should not automatically be assumed to provide identical experiences.

Accessibility can also encourage greater creativity. A client confined to bed might create small clay impressions from leaves brought with consent. Someone living in a dense urban area might photograph weeds growing through pavement cracks and build a collage about persistence. A person who dislikes outdoor settings may prefer wood, cotton, dried herbs, or other familiar organic materials inside the studio.

Nature-based practice becomes richer when “nature” is not imagined exclusively as distant wilderness.

Ethical Collection and Respect for the Living Environment

Using nature therapeutically carries an ecological responsibility. A session intended to create connection with the natural world should not encourage unnecessary damage to that world. Materials can usually be gathered from what has already fallen rather than cutting living plants. Local rules regarding shells, stones, flowers, feathers, protected species, parks, and conservation areas should be respected. Some objects that appear harmless to collect may have ecological or legal significance.

The American Art Therapy Association's discussion of eco-art therapy emphasizes sensitive collection and the importance of not taking the last of available natural material. This principle can itself become part of the therapeutic approach. Instead of treating the environment as an unlimited supply cupboard, clients can practice noticing, choosing, and taking only what is appropriate.

Temporary art offers another option. Leaves and stones can be arranged, photographed if desired, and then left in place. This changes the relationship between creativity and ownership. The art does not have to be removed from the landscape to matter.

For some people, creating something they cannot keep may become an exploration of impermanence. For others, it simply feels environmentally respectful. Either way, the ethical dimension reminds us that nature-based therapy involves relationship rather than extraction.

When Nature Does Not Feel Grounding

It is tempting to assume that natural settings are universally calming, but they are not. Someone who survived a natural disaster may respond strongly to wind, water, forests, or storms. A person who experienced violence outdoors may feel safer inside. Someone with severe allergies may associate flowers with physical distress. Insects, soil, darkness, open spaces, particular animals, or certain textures may evoke discomfort rather than relaxation.

Trauma-informed practice therefore requires choice.

A client should not be told that touching soil, walking barefoot, hugging a tree, or closing their eyes outdoors will necessarily calm them. The therapist can offer possibilities and observe the person's response. If a smooth manufactured object feels safer than a pinecone, then the manufactured object may be the more appropriate grounding material.

The same principle applies to sensory exercises. A strong smell that helps one client orient could overwhelm another. A rough surface may feel stimulating to one person and intolerable to someone with sensory sensitivity.

Grounding is relational and individualized. The question is not, “Is nature calming?” It is, “What helps this particular person feel more present, oriented, and able to remain within a workable range of emotional activation?”

Nature offers many possibilities, but it should never become another therapeutic prescription the client is expected to enjoy.

From Grounding to Expression

One of the strengths of combining grounding and art-making is that the process does not need to stop once the client feels more oriented. Sensory attention can become the doorway into expression.

A person might begin by holding a stone and noticing its physical qualities. After a few minutes, they may paint the feeling associated with its weight. Someone else may study the texture of bark and use charcoal to create a pattern that gradually becomes an image of tension. A client may sort leaves quietly by color before realizing that they want to arrange them into a timeline of a difficult year.

The progression can move from sensation to image, from image to metaphor, and from metaphor to language.

This order can be particularly useful for people who arrive in therapy already overwhelmed by words. They may have explained their situation repeatedly to doctors, family members, colleagues, or themselves. Beginning instead with texture gives the mind another route into the experience.

The art therapist does not need to rush the transition. If the client spends an entire session arranging stones and says very little, the work may still be meaningful. Silence combined with focused sensory engagement can sometimes offer something that immediate verbal analysis cannot.

The Therapist's Role: Curiosity Instead of Symbolic Certainty

Nature is full of culturally familiar symbols. Trees are associated with growth, stones with strength, water with emotion, roots with ancestry, flowers with beauty, and seasons with life stages. These associations can be useful starting points in literature and art, but therapy becomes reductive when symbolic meanings are imposed.

A root does not always mean family.

A dead leaf does not always mean loss.

A stone does not always mean resilience.

The therapist can instead ask, “What does this object bring up for you?” or “What made you choose this?” This allows symbolic meaning to remain personal and contextual.

A client who selects a stone may associate it with emotional coldness rather than strength. Roots might symbolize being trapped rather than belonging. A field of flowers might represent grief because it resembles the cemetery where someone was buried. The client's meaning takes priority.

This stance turns nature from a symbolic dictionary into a language that therapist and client explore together.

Conclusion: Returning Attention to What Is Here

Nature-based art therapy does not depend on extraordinary landscapes. It can begin with something as small as a leaf, a stone, a handful of clay, or the texture of bark. What matters is the quality of attention that develops around the material and the possibilities it creates for sensory awareness, creative expression, metaphor, and relationship.

Psychological grounding helps redirect attention toward the present when internal experience has become overwhelming. Natural materials can support this process because they provide immediate sensory information: weight, temperature, texture, shape, sound, color, resistance, and movement. The person does not have to invent these qualities. They are already there, waiting to be noticed.

Research on nature exposure provides plausible context for why this can matter. Studies have linked contact with natural environments to attention restoration, changes in mood, reduced rumination, and broader indicators of psychological well-being, while reviews suggest potentially meaningful associations between nature exposure and mental health (Berman et al., 2008; Bettmann et al., 2024; Bratman et al., 2015; Jimenez et al., 2021). At the same time, nature-based art therapy remains a developing research field, and current evidence does not justify presenting leaves, stones, forests, or creative activities as universal treatments (Gulbe et al., 2025).

Their therapeutic value is more subtle and, perhaps, more interesting. A leaf can invite someone to look closely when their thoughts are moving too quickly. A stone can provide weight when experience feels unreal or scattered. Clay can receive the impression of bark and hold a trace of something that is no longer physically present. A group of seedpods can become a pattern, a memory, a metaphor, or simply several objects that make an interesting sound when moved.

In each case, the natural material offers something concrete enough to touch and open enough to imagine with.

The goal is not to escape psychological difficulty by retreating into nature, nor is it to insist that every natural object contains a lesson about healing. It is to recognize that therapy does not happen only through explanation. Sometimes psychological work begins with noticing a temperature, following a line with the eyes, feeling resistance under the fingertips, or realizing that for several moments the mind has stopped circling around the same question.

A person looks at the leaf in their hand and notices its veins, its torn edge, the place where green has turned to brown, and the tiny spaces where light passes through.

The problem that brought them to therapy is still there.

But so are they.

And for this moment, they are here.
